  1. Values in the same row with the same superscripts are not significantly different (P > 0.05).
  2. See Table 1 for diet abbreviations.
  3. MIBW (g): Mean initial body weight, MFBW (g): Mean final body weight
  4. CF: Condition factor =100 × (final weight (g)) × (fork length (cm))−3.
  5. SGR (%day-1): Specific growth rate = [Ln(final weight) − Ln(initial weight)] × (number of days)−1 × 100.
  6. WG (%): Weight Gain = (final weight − initial weight) × (initial weight)−1 × 100
  7. FCR: Feed conversion ratio = (dry feed fed) × (wet weight gain)−1.
  8. SR (%): Survival rate = number of fish in each group remaining on day 56 − (initial number of fish)-1 × 100.
  9. HSI (%): Hepatosomatic index = (weight of liver) × (total fish weight)−1 × 100.
  10. PER: Protein efficiency ratio = (final weight − initial weight) × (mass of protein fed)−1.
